有什么可以帮助我理解为什么我的应用程序在运行时抛出这个错误吗？

mvn gwt:compile

深入观察代码，我可以看到：

代码语言：javascript
复制
[ERROR] Resource org/jboss/errai/ui/demo/client/local/PasswordRequiredPage.html not found. Is the name specified as Class.getResource() would expect?

但是，html页面上有相应的PasswordRequiredPage.java：

PasswordRequiredPage.java

代码语言：javascript
复制
@Dependent
@Templated("#passwordrequired")
@Page
public class PasswordRequiredPage extends Composite {
}

PasswordRequiredPage.html

代码语言：javascript
复制
<div data-field="passwordrequired">
 <!-- Content -->
</div>

我的申请有什么问题吗？我已经做了：

代码语言：javascript
复制
 - mvn clean (SUCCESS)
 - mvn gwt:compile (FAIL)
 - mvn gwt:run (FAILE)
java

尽管PasswordRequiredPage.html位于与PasswordRequiredPage.java相同的文件夹中，但当gwt-编译器运行时，它应该在类路径中。

您可以通过两种方式修复它：

  1. 将PasswordRequiredPage.html复制到java编译器生成PasswordRequiredPage.class的文件夹中，配置maven-资源-插件 (目标复制资源)
  2. 将.html所在的源文件夹添加到编译类路径中。

我从未使用过Errai，也不知道它是如何使用gwt编译器的，但出于某种原因，它正在将.java文件添加到类路径(可能也包括.css和.png )，但没有.html文件。

也许，您必须将路径添加到@Page注释中；就像它出现在官方指南。中一样。

不确定，但据我所知，您应该在HTML中使用id属性来进行模板开发。数据字段用于在相应的java代码中注入小部件或构造元素，使其具有句柄。

试一试

代码语言：javascript
复制
<div id="passwordrequired">
 <!-- Content -->
</div>

在java代码中，“这个”将对应于根小部件/复合。
